Effects of Bloom Thinning with Lime Sulfur on Fruit Set, Yield, and Fruit Quality Attributes of ‘RubyS’ Apples

Bloom thinning is an important practice that influences the profitability of orchard. Hence, we assessed effect chemical bloom on efficiency and fruit quality ‘RubyS’ apples. Lime sulfur was applied as a agent at 1, 1 + 3, 2 4 days after full (DAFB), non-bloom trees were used controls. Compared to control treatments DAFB DAFB, application 3 greatly decreased number fruits per cluster in both terminal lateral flowers. Although flower, it did not affect flower when compared control. At harvest, tree (fruits/ tree) yield (kg/ significantly higher than bloom-thinned trees. However, attributes including weight size, flesh firmness, soluble solids content, area red-blushed surface, a* value improved by DAFB. Therefore, this study suggested applying could serve effective treatment manage crop load improve apple fruits.
